Using intelligent network processing, call notification allows a subscriber to determine the name and telephone number of one or more numbers of recent parties to call the subscriber. An incoming call to the subscriber's number activates a terminating attempt type trigger in the central office serving the subscriber. The trigger causes communication between that office and a service control point (SCP). Under instructions from the SCP, the central office indicates a disposition event regarding the call, e.g., whether the line was busy or there was no answer. If the subscriber's line is busy or does not answer, the SCP records at least the telephone number of the caller and the time and date of the call. Later, the subscriber dials a feature code, and the SCP instructs the central office to route the call to an intelligent peripheral (IP). The SCP polls a line identification database (LIDB) to obtain name information associated with the caller's number and supplies the number, name, date and time to the IP. The IP plays an announcement of the call information and offers the subscriber the option to place a call back to the number of the original caller and/or to initiate a call to voice mail.
Legal claims defining the scope of protection, as filed with the USPTO.

8. A call notification method as in claim 7 , wherein the step of providing an audible announcement comprises: establishing a call connection from the subscriber's link through the public switched telephone network to an announcement platform; providing the identification derived from the recorded information to the announcement platform; and sending the audible announcement from the announcement platform over the established call connection.
9. A call notification method as in claim 1 , further comprising: receiving a call-back request from the subscriber's link responsive to the audible announcement of the identification; and in response to the receipt of the call-back request, automatically initiating a call through the communication network from the subscriber's link to a link associated with the recorded information.
10. A call notification method as in claim 9 , wherein the step of receiving a call-back request comprises recognizing a spoken request.
11. A call notification method as in claim 1 , further comprising: receiving a request for connection to a messaging system from the subscriber's link after the audible announcement of the identification; and in response to the receipt of the request, automatically initiating a call through the communication network from the subscriber's link to the messaging system.
12. A call notification method as in claim 11 , wherein the step of receiving a request comprises recognizing a spoken request.
13. A call notification method as in claim 11 , wherein the messaging system comprises a voice mail system.
14. A method of providing waiting call notification, comprising: detecting a call to a subscriber's number at an office of a telephone network, the office providing service over a telephone link for the subscriber; if the subscriber's telephone link is busy, recording information relating to the detected call in a control point of the telephone network; sending a call waiting signal over the subscriber's telephone link; in response to a later request from the subscriber's telephone link, establishing a call connection of the subscriber's telephone link to a message platform; and transmitting a message including an identification derived from the recorded information to a requesting party through the call connection and the subscriber's telephone link.
15. A method as in claim 14 , wherein the step of recording information comprises: sending the information over a signaling link to a service control point of the telephone network; and recording the information in the service control point.
16. A method as in claim 15 , wherein the step of transmitting a message comprises: deriving the identification from the recorded information and transmitting the derived identification over a data link to the message platform; and converting the identification to a format presentable to the requesting party and sending the converted identification through the call connection and the subscriber's telephone link.
17. A method as in claim 16 , wherein the converted identification comprises an audible announcement of the identification.
18. A method as in claim 14 , further comprising: receiving a call-back request via the subscriber's telephone link and the established call connection; and in response to the call-back request, initiating a call from the subscriber's telephone link to a telephone link associated with the recorded information.
19. A method as in claim 18 , wherein the step of receiving a call-back request comprises recognizing a spoken request from the party received via the established call connection.
20. A method as in claim 14 , further comprising: receiving a voice-mail request via the subscriber's telephone link and the established call connection; and in response to the voice-mail request, initiating a call from the subscriber's telephone link to a voice messaging system providing voice mail service for the subscriber.
